Re: Access to IrDA PHY Level

Check out the PF_PACKET interface documented in the packet(7) man page.
You can open a packet socket with SOCK_RAW and send pretty much
raw frames out an IrDA device from userspace.

You can use the SIOCSBANDWIDTH ioctl on the packet to set the data rate.
You might have to explore the linux/irda.h header directly and
if_irda_req struct for details as I don't believe a lot of this low
level stuff is documented formally.

Throughout its 18-year history, RSA Conference consistently attracts the
world's best and brightest in the field, creating opportunities for Conference
attendees to learn about information security's most important issues through
interactions with peers, luminaries and emerging and established companies.
